我认为问题不在于方言，因为它创建了表，只有数据没有加载到表中。我正在使用org。冬眠地方话mysql8dialent，如果我更改dialent的值，它不会创建表。任何反馈都将受到重视！非常感谢。

插入查询似乎已被读取为3个单独的查询。尝试将import.sql更改为：

insert into currency_exchange(id, currency_from, currency_to) values (10001, 'USD', 'INR');

虽然我不知道为什么会出现错误，但我已经用最新的Hibernate ORM 5.6.9对其进行了测试。决赛，一切顺利。

也许这是您使用的版本中的错误（应该是5.4.32）。或者import.sql?中还有其他东西
